Description
Choline hydroxide is an aqueous solution supplied at 46,5–50,0 % in water, identified by CAS number 123-41-1 and empirical formula C₅H₁₅NO₂. With a molar mass of 121,18 g/mol and a density of 1,08 g/cm³, this strong organic base is used in organic synthesis, phase-transfer chemistry, catalyst preparation and specialised aqueous formulations. The defined concentration range supports reproducible dosing when preparing reaction media, ionic liquids precursors or quaternary ammonium systems. Careful handling is appropriate given its basic character and solution form. Choline hydroxide from manufacturer Carl ROTH is a standard fine chemical for research and industrial laboratories that require a controlled aqueous choline base. Reference the CAS number, concentration band and density when transferring methods or calculating molar amounts to maintain consistency across batches and analytical documentation.

Questions about Choline hydroxide, 46,5-50,0 % in water, 50 ml, glass
What is this article?
Choline hydroxide, 46,5-50,0 % in water, 50 ml, glass is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Bases & alkalis, inside Acids & bases, in Lab chemicals.
A base or an alkali is sodium hydroxide, potassium hydroxide, ammonia and their relatives, as solid or as solution. The carbonate that a hydroxide picks up from the air changes a titre. Concentration and purity are the specification. Concentrated alkalis attack skin and aluminium.
An acid donates a proton. A base accepts one. In the bottle, the practical differences are the concentration, the purity and the anion or cation that comes along. Concentrated mineral acids are a different article from a dilute volumetric solution. The water in the acid, and the trace metals, decide whether it can be used for analysis. Check the substance on PubChem and the classification on ECHA CLP. Transport is the UNECE dangerous-goods framework. The legal texts are the CLP Regulation and REACH.
